<u>Answer:</u> The correct answer is the dependent variable changes in response to changes in the independent variable.
<u>Explanation:</u>
Dependent variable is defined as the variable which varies in accordance to the change in independent variable. For Example: Current is a dependent variable and voltage is the independent variable according to Ohm's law.
I ∝ V
Independent variable is defined as the variable which does not change in accordance to any other variable in a given scientific experiment. For Example: Time (as expressed in seconds)
Hence, the correct answer is the dependent variable changes in response to changes in the independent variable.
Answer:
Metales alcalinos
El grupo 1A (o IA) de la tabla periódica son los metales alcalinos: hidrógeno (H), litio (Li), sodio (Na), potasio (K), rubidio (Rb), cesio (Cs) y francio (Fr). . Estos son (excepto el hidrógeno) metales suaves, brillantes, de bajo punto de fusión y altamente reactivos, que se empañan cuando se exponen al aire.
Explanation:
Molecules in cells that help build up and break down things
Answer:
B
Explanation:
Wall cell has to be strong to bring protection to the cell. In general it is made of beta-glycosidic bonds.
Storage polysaccharides, are a source of available energy for the cell in any moment. Therefore, the bonds of storage polysaccharides need to be weak. In that way, when the cell needs energy from carbohydrates, it is not going to spend so much energy trying to break the bond.
